Card Appearances:Fenrir the Nordic Wolf

In episode 129, Halldor uses this card during his Turbo Duel against Yusei Fudo. He adds this card from his Deck to his hand via "Gleipnir, the Fetters of Fenrir". He then Special Summons this card to Yusei's side of the field via its own effect as he controls a face-up Divine-Beast type monster. Halldor explains to Yusei if he were to enter his Battle Phase while "Fenrir" is face-up, all of Yusei's monsters will switch to Attack Position which would activate the effect of "Jormungardr the Nordic Serpent" (this would inflict 3000 damage to Yusei and defeat him). He also explains that if "Fenrir the Nordic Wolf" were to deal Battle Damage to him, Yusei would take the same amount of Battle Damage too. Later Yusei activates "Speed Spell - Star Force" to banish this card and increase the ATK of "Shooting Star Dragon" by this card's Level times 100 until the End Phase. Since this card is Level 10, "Shooting Star Dragon" gains 1000 ATK.
